Intent

The intent of this manual is to act as an introductory guide to the STREAMS programmer. It is intended to be read alone and is not intended to replace or supplement the OpenSS7 IPERF Utility manual pages. For a reference for writing code, the manual pages (see STREAMS(9)) provide a better reference to the programmer. Although this describes the features of the OpenSS7 IPERF Utility package, OpenSS7 Corporation is under no obligation to provide any software, system or feature listed herein.

Audience

This manual is intended for a highly technical audience. The reader should already be familiar with Linux network programming, the Linux file system, character devices, driver input and output, interrupts, software interrupt handling, scheduling, process contexts, multiprocessor locks, etc.

The guide is intended for network and systems programmers, who use the OpenSS7 IPERF Utility mechanism at user level for Linux and UNIX system communication services.

Readers of the guide are expected to possess prior knowledge of the Linux and UNIX system, programming, networking, and data communication.

Quick Start Guide

OpenSS7 IPERF Utility

Package iperf-2.0.8 was released under AGPLv3 2008-10-31.

Iperf is a general purpose tool for measuring bandwidth and performance of the Internet Protocol suite. The OpenSS7 Modified OpenSS7 IPERF Utility package is an OpenSS7 Project release of the DAST iperf package configured to run with OpenSS7 Linux Native Stream Control Transmission Protocol (SCTP).

The OpenSS7 IPERF Utility package provides primarily the iperf(1), C++ Language program that acts as either an Iperf server or client for testing connections and networking. The iperf(1) program is executed on one host in server mode and then executed on another host in client mode. Characteristics of the connection or association can be altered when formed. Reporting formats and sample intervals can also be altered when the connection or association is formed.

This is a fork of the Iperf package released by the University of Illinois modified by the OpenSS7 Project for use with OpenSS7 SCTP (Stream Control Transmission Protocol). This OpenSS7 release of the package is based on the Iperf-2.0.0 release from the University of Illinois.

Modifications to the package are derived from the OpenSS7 SCTP implementation and are released under the GNU Affero General Public License (AGPL) Version 3. The Iperf tool itself is licensed under specific terms by the University of Illinois. Please see LICENSES for the University of Illinois Iperf copyright notices and licensing restrictions. The Iperf tool is:

Copyright 1999, 2000, 2001, 2002, 2003, 2004
The Board of Trustees of the University of Illinois
All rights reserved

See University of Illinois License in the LICENSES file for complete details.

Please note that this modified version of the Iperf package is not endorsed by the University of Illinois or DAST in any way and that neither the original copyright holders nor OpenSS7 Corporation will take any responsibility in it.

This distribution is only currently applicable to Linux 2.4 kernels and was targeted at ix86, x86_64, ppc and ppc64 architectures, but should build and install for other architectures as well.

Release

This is the iperf-2.0.8 package, released 2008-10-31. This ‘2.0.8’ release, and the latest version, can be obtained from the download area of The OpenSS7 Project website using a command such as:

     $> wget http://www.openss7.org/tarballs/iperf-2.0.8.tar.bz2

The release is available as an autoconf(1) tarball, src.rpm or dsc, as a set of binary rpms or debs, or as a yum(8) or apt(8) repository. See the download page for the autoconf(1) tarballs, src.rpms, dscs, or repository access instructions. See the iperf package page for tarballs, source and binary packages.

Please see the NEWS file for release notes and history of user visible changes for the current version, and the ChangeLog file for a more detailed history of implementation changes. The TODO file lists features not yet implemented and other outstanding items.

Please see the INSTALL, INSTALL-iperf and README-make, files (or see Installation) for installation instructions.

When working from cvs(1) or git(1), please see the README-cvs, file (or see Downloading from CVS). An abbreviated installation procedure that works for most applications appears below.

This release of the package is published strictly under Version 3 of the GNU Affero Public License which can be found in the file COPYING. Package specific licensing terms (if any) can be found in the file LICENSES. Please respect these licensing arrangements. If you are interested in different licensing terms, please contact the copyright holder, or OpenSS7 Corporation <sales@openss7.com>.

See README-alpha (if it exists) for alpha release information.

Prerequisites

The quickest and easiest way to ensure that all prerequisites are met is to download and install this package from within the OpenSS7 Master Package, openss7-0.9.2.G, instead of separately.

Prerequisites for the OpenSS7 IPERF Utility package are as follows:

  1. Linux distribution, somewhat Linux Standards Base compliant, with a 2.4 or 2.6 kernel and the appropriate tool chain for compiling out-of-tree kernel modules. Most recent Linux distributions are usable out of the box, but some development packages must be installed. For more information, see Compatibility.

    − A fairly LSB compliant GNU/Linux distribution.2
    − Linux 2.4 kernel (2.4.10 - 2.4.27), or
    − Linux 2.6 kernel (2.6.3 - 2.6.26);
    − glibc2 or better.
    − GNU groff (for man pages).3
    − GNU texinfo (for info files).

(Note that although the original University of Illinois DAST Iperf builds and installs on a number of operating systems, the OpenSS7 modified version only currently builds and installs on Linux.)

(Note: If you acquired iperf a part of the OpenSS7 Master Package, then the dependencies listed below will already have been met by unpacking the master package.)

  1. OpenSS7 Sockets SCTP, sctp-0.2.27. (Optional.)

When configuring and building multiple OpenSS7 Project release packages, place all of the source packages (unpacked tarballs) at the same directory level and all build directories at the same directory level (e.g. all source packages under /usr/src).

When installing packages that install as kernel modules, it is necessary to have the correct kernel development package installed. For the following distributions, use the following commands:

     Ubuntu:  $> apt-get install linux-headers
     Debian:  $> apt-get install kernel-headers
     Fedora:  $> yum install kernel-devel

You also need the same version of gcc(1) compiler with which the kernel was built. If it is not the default, add ‘CC=kgcc’ on the line after ‘./configure’, for example:

     $> ../iperf-2.0.8/configure CC='gcc-3.4'

Installation

The following commands will download, configure, build, check, install, validate, uninstall and remove the package:

     $> wget http://www.openss7.org/tarballs/iperf-2.0.8.tar.bz2
     $> tar -xjvf iperf-2.0.8.tar.bz2
     $> mkdir build
     $> pushd build
     $> ../iperf-2.0.8/configure --enable-autotest
     $> make
     $> make check
     $> sudo make install
     $> sudo make installcheck
     $> sudo make uninstall
     $> popd
     $> sudo rm -rf build
     $> rm -rf iperf-2.0.8
     $> rm -f iperf-2.0.8.tar.bz2

If you have problems, try building with the logging targets instead. If the make of a logging target fails, an automatic problem report will be generated that can be mailed to The OpenSS7 Project.4 Installation steps using the logging targets proceed as follows:

     $> wget http://www.openss7.org/tarballs/iperf-2.0.8.tar.bz2
     $> tar -xjvf iperf-2.0.8.tar.bz2
     $> mkdir build
     $> pushd build
     $> ../iperf-2.0.8/configure --enable-autotest
     $> make compile.log
     $> make check.log
     $> sudo make install.log
     $> sudo make installcheck.log
     $> sudo make uninstall.log
     $> popd
     $> sudo rm -rf build
     $> rm -rf iperf-2.0.8
     $> rm -f iperf-2.0.8.tar.bz2

See README-make for additional specialized make targets.

For custom applications, see the INSTALL and INSTALL-iperf files or the see Installation, as listed below. If you encounter troubles, see Troubleshooting, before issuing a bug report.

Brief Installation Instructions

The OpenSS7 IPERF Utility package is available from the downloads area of The OpenSS7 Project website using a command such as:

     $> wget http://www.openss7.org/tarballs/iperf-2.0.8.tar.bz2

Unpack the tarball using a command such as:

     $> tar -xjvf iperf-2.0.8.tar.bz2

The tarball will unpack into the relative subdirectory named after the package name: iperf-2.0.8.

The package builds using the GNU autoconf utilities and the configure script. To build the package, we recommend using a separate build directory as follows:

     $> mkdir build
     $> cd build
     $> ../iperf-2.0.8/configure

In general, the package configures and builds without adding any special options to the configure script. For general options to the configure script, see the GNU INSTALL file in the distribution:

     $> less ../iperf-2.0.8/INSTALL

For specific options to the configure script, see the INSTALL-iperf file in the distribution, or simply execute the configure script with the --help option like so:

     $> ../iperf-2.0.8/configure --help

After configuring the package, the package can be compiled simply by issuing the ‘make’ command:

     $> make

Some specialized makefile targets exists, see the README-make file in the distribution or simply invoke the ‘help’ target like so:

     $> make help | less

After successfully building the package, the package can be checked by invoking the ‘check’ make target like so:

     $> make check

After successfully checking the package, the package can be installed by invoking the ‘install’ make target (as root) like so:

     $> sudo make install

The test suites that ship with the package can be invoked after the package has been installed by invoking the ‘installcheck’ target. This target can either be invoked as root, or as a normal user, like so:

     $> make installcheck

(Note: you must add the --enable-autotest flag to configure, above for the test suites to be invoked with ‘make installcheck’.)

The package can be cleanly removed by invoking the ‘uninstall’ target (as root):

     $> sudo make uninstall

Then the build directory and tarball can be simply removed:

     $> cd ..
     $> rm -rf build
     $> rm -rf iperf-2.0.8
     $> rm -f iperf-2.0.8.tar.bz2

Detailed Installation Instructions

More detailed installation instructions can be found in the Installation, contained in the distribution in ‘text’, ‘info’, ‘html’ and ‘pdf’ formats:

     $> cd ../iperf-2.0.8
     $> less doc/manual/iperf.txt
     $> lynx doc/manual/iperf.html
     $> info doc/manual/iperf.info
     $> xpdf doc/manual/iperf.pdf

The ‘text’ version of the manual is always available in the MANUAL file in the release.

The current manual is also always available online from The OpenSS7 Project website at:

This is the OpenSS7 Release of the OpenSS7 IPERF Utility package, modified for use with OpenSS7 Stream Control Transmission Protocol (SCTP) Linux Native Kernel.

The purpose of providing a separate release of this package was to provide support for SCTP as well as providing the ability to use GNU autoconf tools for maintenance and binary RPM release of the package.

The following sections provide information on OpenSS7 IPERF Utility releases as well as compatibility information of OpenSS7 release to the original UI DAST releases of the OpenSS7 IPERF Utility package.

5.1 Prerequisites

The quickest and easiest way to ensure that all prerequisites are met is to download and install this package from within the OpenSS7 Master Package, openss7-0.9.2.G, instead of separately.

Prerequisites for the OpenSS7 IPERF Utility package are as follows:

  1. Linux distribution, somewhat Linux Standards Base compliant, with a 2.4 or 2.6 kernel and the appropriate tool chain for compiling out-of-tree kernel modules. Most recent Linux distributions are usable out of the box, but some development packages must be installed. For more information, see Compatibility.

    − A fairly LSB compliant GNU/Linux distribution.6
    − Linux 2.4 kernel (2.4.10 - 2.4.27), or

5.2.2 Architectures

The OpenSS7 IPERF Utility package compiles and installs on a wide range of architectures. Although it is believed that the package will work on all architectures supported by the Linux kernel being used, validation testing has only been performed with the following architectures:

  • ix86
  • x86_64
  • ppc (MPC 860)
  • ppc64

32-bit compatibility validation testing is performed on all 64-bit architectures supporting 32-bit compatibility. If you would like to validate an OpenSS7 package on a specific machine architecture, you are welcome to sponsor the project with a test machine.

5.2.3 UI Iperf

This section addresses compatibility issues between OpenSS7 and University of Illinois DAST releases of iperf.

iperf-2.0.8 and Iperf Compatibility

OpenSS7 modifications to support SCTP does not alter the data structures nor fundamental operation. New structures and test definitions have been added for SCTP that are largely consistent with those of TCP.

Specifically, an iperf-2.0 client should be able to connect and perform tests with an iperf-2.0.8 server. Also, an iperf-2.0.8 client should be able to connect and perform tests (other than SCTP) with an iperf-2.0 server.

iperf-2.0.8 and Option Compatibility

OpenSS7 releases provide all options compiled-in to the program. This obviates the need for editing makefiles and recompiling the program from source as is described in the University of Illinois DAST documentation. Additional options were provided to support SCTP.

iperf-2.0.8 and SCTP Compatibility

SCTP API tests are (likely) only compatible with the OpenSS7 Sockets implementations of SCTP. The reason for this is that the OpenSS7 Sockets implementations use the POSIX standard socket API rather than the non-standard socket API described in documents such as draft-stewart-tsvwg-sctpsocket-xx.txt.

5.3 Release Notes

The sections that follow provide information on OpenSS7 releases of the OpenSS7 IPERF Utility package as well as compatibility information of OpenSS7 releases to the original University of Illinois releases.

All RPM release numbers will be -1$(PACKAGE_RPMEXTRA) and all Debian release numbers will be _0. If you wish to apply patches and release the package, please bump up the release number and apply a suitable release suffix for your organization. We leave Debian release number _1 reserved for your use, so you can still bundle the source in the .dsc file.

Initial release iperf-2.0.1-1

Initial autoconf/rpm packaging release of Iperf.

This is an autoconf/rpm release of Iperf suitable for use with OpenSS7 Linux Native SCTP (Stream Control Transmission Protocol). It is usable for performance testing the SCTP application as well as supporting all other Iperf TCP and UDP testing.

Not publicly released.

5.4 Maturity

The OpenSS7 Project adheres to the following release philosophy:

  • pre-alpha release
  • alpha release
  • beta release
  • gamma release
  • production release
  • unstable release

5.4.1 Pre-Alpha Releases

Pre-alpha releases are releases that have received no testing whatsoever. Code in the release is not even known to configure or compile. The purpose of a pre-alpha release is to make code and documentation available for inspection only, and to solicit comments on the design approach or other characteristics of the software package.

Pre-alpha release packages ship containing warnings recommending that the user not even execute the contained code.

5.4.2 Alpha Releases

Alpha releases are releases that have received little to no testing, or that have been tested and contains known bugs or defects that make the package unsuitable even for testing. The purpose for an alpha release are the same as for the pre-alpha release, with the additional purpose that it is an early release of partially functional code that has problems that an external developer might be willing to fix themselves and contribute back to the project.

Alpha release packages ship containing warnings that executing the code can crash machines and might possibly do damage to systems upon which it is executed.

5.4.3 Beta Releases

Beta releases are releases that have received some testing, but the testing to date is not exhaustive. Beta release packages do not ship with known defects. All known defects are resolved before distribution; however, as exhaustive testing has not been performed, unknown defects may exist. The purpose for a beta release is to provide a baseline for other organizations to participate in the rigorous testing of the package.

Beta release packages ship containing warnings that the package has not been exhaustively tested and that the package may cause systems to crash. Suitability of software in this category for production use is not advised by the project; however, as always, is at the discretion of the user of the software.

5.4.4 Gamma Releases

Gamma releases are releases that have received exhaustive testing within the project, but external testing has been minimal. Gamma release packages do not ship with known defects. As exhaustive internal testing has been performed, unknown defects should be few. Please remember that there is NO WARRANTY on public release packages.

Gamma release packages typically resolve problems in previous beta releases, and might not have had full regression testing performed. Suitability of software in this category for production use is at the discretion of the user of the software. The OpenSS7 Project recommends that the complete validation test suites provided with the package be performed and pass on target systems before considering production use.

5.4.5 Production Releases

Production releases are releases that have received exhaustive testing within the project and validated on specific distributions and architectures. Production release packages do not ship with known defects. Please remember that there is NO WARRANTY on public release packages.

Production packages ship containing a list of validated distributions and architectures. Full regression testing of any maintenance changes is performed. Suitability of software in this category for production use on the specified target distributions and architectures is at the discretion of the user. It should not be necessary to preform validation tests on the set of supported target systems before considering production use.

5.4.6 Unstable Releases

Unstable releases are releases that have received extensive testing within the project and validated on a a wide range of distributions and architectures; however, is has tested unstable and found to be suffering from critical problems and issues that cannot be resolved. Maintenance of the package has proved impossible. Unstable release packages ship with known defects (and loud warnings). Suitability of software in this category for production use is at the discretion of the user of the software. The OpenSS7 Project recommends that the problems and issues be closely examined before this software is used even in a non-production environment. Each failing test scenario should be completely avoided by the application. OpenSS7 beta software is more stable that software in this category.

5.5 Bugs

5.5.1 Defect Notices

OpenSS7 IPERF Utility could contain unknown defects. This is a beta release. Some defects could be harmful. Validation testing has been performed by the OpenSS7 Project on this software for only a restricted set of systems. The software might fail to configure or compile on other systems. The OpenSS7 Project recommends that you do not use this software for purposes other than validation testing and evaluation, and then only with care. Use at your own risk. Remember that there is NO WARRANTY.9

This software is beta software. As such, it might crash your kernel. Installation of the software might mangle your header files or Linux distribution in such a way as to make it unusable. Crashes could lock your system and rebooting the system might not repair the problem. You can possibly lose all the data on your system. Because this software might crash your kernel, the resulting unstable system could possibly destroy computer hardware or peripherals making them unusable. You might void the warranty on any system on which you run this software. YOU HAVE BEEN WARNED.

5.5.2 Known Defects

With the exception of packages not originally created by the OpenSS7 Project, the OpenSS7 Project software does not ship with known bugs in any release stage except pre-alpha. OpenSS7 IPERF Utility had no known bugs at the time of release.

Nevertheless, the OpenSS7 Project does not validate the OpenSS7 IPERF Utility package, but simply uses it for benchmark performance testing. Following are some of the expected difficulties with the package that have not yet been discovered:

  1. No bug fixes from the original Iperf development stream have been rolled back into this release. Therefore, any bugs reported on the regular Iperf release package probably still exist unfixed in this release package.

5.5.3 Defect History

This section contains historical bugs that were encountered during development and their resolutions. This list serves two purposes:

  1. It captures bugs encountered between releases during development that could possibly reoccur (and the Moon is made of blue cheese). It therefore provides a place for users to look if they encounter a problem.
  2. It provides a low overhead bug list between releases for developers to use as a TODO list.

5.6 Schedule

Current Plan

There is no current plan for the iperf package beyond minor distribution maintenance. The package tests the OpenSS7 Linux Native Sockets version of sctp (‘sctp’ package) nicely, but that package only runs on 2.4 kernels. When the strsock package is complete for Linux Fast-STREAMS, the OpenSS7 Project will likely haul this back out and use it for testing the STREAMS versions of UDP, TCP and SCTP using the socklib interface. But, the strsock package completion itself is not planned, so you can only likely expect maintenance releases of this package. The package could be extended to test lksctp as well, however, comparisons between lksctp and sctp can only be done on 2.4 kernels for now. This type of work has been mooted by the current popularity of 2.6 kernels.

Things to Do
  • Write a texinfo manual for Iperf.

    *done*

    You are reading it.

  • Merge upstream changes from the latest University of Illinois release of the Iperf package into the OpenSS7 Modified version. It would really like to do this but don't have the time for it right now. If someone is willing to dive in and give this a try, send me the patches.
  • Iperf is capable of performing performance testing on lksctp as well. I would like to modify the OpenSS7 version of Iperf to support both so that performance comparison testing can be done between lkstcp (which sucks of course) and OpenSS7.

6 Installation

6.1 Repositories

The OpenSS7 IPERF Utility package release can be accessed from the repositories of The OpenSS7 Project. For rpm(1) based systems, the package is available in a yum(8) repository based on repomd XML and may also be accessed using zypper(8) or yast(8). For dpkg(1) based systems, the package is available in a apt(8) repository.

By far the easiest (most repeatable and manageable) form for installing and using OpenSS7 packages is to install packages from the yum(8) or apt(8) repositories. If your distribution does not support yum(8), zypper(8), yast(8) or apt(8), then it is still possible to install the RPMs or DEBs from the repositories using rpm(1), dpkg(1); or by using wget(1) and then installing them from RPM or DEB using rpm(1) or dpkg(1) locally.

If binaries are not available for your distribution or specific kernel, but your distribution supports rpm(1) or dpkg(1), the next best method for installing and using OpenSS7 packages is to download and rebuild the source RPMs or DSCs from the repository. This can also be performed with yum(8), zypper(8), yast(8), apt(8); or directly using wget(1), rpm(1) or dpkg(1).

If your architecture does not support rpm(1) or dpkg(1) at all, or you have special needs (such as cross-compiling for embedded targets), the final resort method is to download, configure, build and install from tarball. In this later case, the easiest way to build and install OpenSS7 packages from tarball is to use the tarball for the OpenSS7 Master Package, openss7-0.9.2.G.

6.1.1 Repositories for YUM

To install or upgrade from the OpenSS7 repomd repositories, you will need a file in your /etc/yum.repo.d/ directory. This file can be obtained directly from the OpenSS7 repository, like so:

     $> REPOS="http://www.openss7.org/repos/rpms"
     $> wget $REPOS/centos/5.2/x86_64/repodata/openss7.repo
     $> sudo cp -f openss7.repo /etc/yum.repo.d/
     $> sudo yum makecache

This example assumes the the distribution is ‘centos’ and the distribution release is ‘5.2’ and the architecture requires is ‘x86_64’. Another example would be $REPOS/i686/suse/11.0/i686/repodata/openss7.repo, for using yum(8) with SUSE.

Once the repository is set up, OpenSS7 includes a number of virtual package definitions that eas the installation and removal of kernel modules, libraries and utilities. Downloading, configuring, building and installation for a single-kernel distribution is as easy as:

     $> sudo yum install iperf

Removing the package is as easy as:

     $> sudo yum remove iperf

If you have difficulty downloading the openss7.repo file, edit the following information into the file and place it into the /etc/yum.repo.d/openss7.repo file:

     -| [openss7]
     -| enabled = 1
     -| name = OpenSS7 Repository
     -| baseurl = http://www.openss7.org/repos/rpms/centos/5.2/x86_64
     -| gpgcheck = 1
     -| gpgkey = http://www.openss7.org/pubkey.asc

Note that it is also possible to point to these repositories as an additional installation source when installing CentOS, RedHat, Fedora, or others. You will have an additional STREAMS category from which to choose installation packages.

Some additional installation real or virtual package names and the installations they accomplish are as follows:

iperf
This package can be used to install or remove the entire OpenSS7 IPERF Utility package. When installing, kernel modules will be installed automatically for the highest version kernel on your system. When removing, all corresponding kernel modules will also be removed.
iperf-devel
This package can be used to install or remove the development components of the OpenSS7 IPERF Utility package. When installing, ‘iperf’ and appropriate kernel module and kernel module development and debug packages will also be installed. When removing, the development package and all kernel module development and debug packages will also be removed.
iperf-2.4.20-28.7
This package can be used to install or remove the package for a specific kernel version. When installing, the ‘iperf’ package will also be installed if necessary. When removing the last kernel module package, the ‘iperf’ package will also be removed.

Note that the version ‘2.4.20-28.7’ is just an example. Use the version returned by ‘$(uname -r)’ for the kernel for which you wish to install or remove the packages.

iperf-2.4.20-28.7-devel
This package can be used to install or remove the development and debug packages for a specific kernel version. When installing, the ‘iperf’ and ‘iperf-devel’ packages will also be installed if necessary. When removing the development and debug for kernel modules for the last kernel, the ‘iperf-devel’ package will also be removed.

Note that the version ‘2.4.20-28.7’ is just an example. Use the version returned by ‘$(uname -r)’ for the kernel for which you wish to install or remove the packages.

For assistance with specific RPMs, see Downloading the Binary RPM.

6.1.2 Repositories for APT

For assistance with specific DEBs, see Downloading the Debian DEB.

6.2 Downloading

The OpenSS7 IPERF Utility package releases can be downloaded from the downloads page of The OpenSS7 Project. The package is available as a binary RPM (for popular architectures) a source RPM, Debian binary DEB and source DSC, or as a tar ball. If you are using a browsable viewer, you can obtain the OpenSS7 release of Iperf from the links in the sections that follow.

By far the easiest (most repeatable and manageable) form for installing and using OpenSS7 packages is to download and install individual packages from binary RPM or DEB. If binary RPMs or DEBs are not available for your distribution, but your distribution supports rpm(1) or dpkg(1), the next best method for installing and using OpenSS7 packages is to download and rebuild the source RPMs or DSCs.

If your architecture does not support rpm(1) or dpkg(1) at all, or you have special needs (such as cross-compiling for embedded targets), the final resort method is to download, configure, build and install from tarball. In this later case, the easiest way to build and install OpenSS7 packages from tarball is to use the tarball for the OpenSS7 Master Package, openss7-0.9.2.G.

6.2.1 Downloading with YUM

OpenSS7 repositories support yum(8) and zypper(8) in repomd XML format as well as YaST and YaST2 formats.

OpenSS7 includes virtual packages that ease the installation and removal of kernel modules, libraries and utilities. Downloading, configuration, building and installation for a signle-kernel distribution installation is as easy as:

     % sudo yum install iperf

This and additional packages for installation are detailed as follows:

iperf
Install this package if you need the runtime iperf package.
          % sudo yum install iperf

This will install the iperf, iperf-lib and iperf-KVERSION RPMs, where ‘KVERSION’ is the highest version number kernel on your system.

Remove this package if you need to remove all vestages of the iperf package.

          % sudo yum remove iperf

This will remove the iperf, iperf-lib, iperf-devel, iperf-KVERSION and iperf-devel-KVERSION RPMs for all kernels on your system.

iperf-devel
Install this package if you need the development iperf package.
          % sudo yum install iperf-devel

This will install the iperf, iperf-lib, iperf-devel, iperf-KVERSION and iperf-devel-KVERSION RPMs, where ‘KVERSION’ is the highest version number kernel on your system.

Remove this package if you do not need development capabilities for the iperf package for any kernel.

          % sudo yum remove iperf-devel

This will remove the iperf-devel and iperf-devel-KVERSION RPMs for all kernels on your system.

iperf-2.4.20-28.7
Install this package if you need the runtime iperf for kernel version ‘2.4.20-28.7’. The value ‘2.4.20-28.7’ is just an example. For the running kernel, you can install the runtime iperf components with:
          % sudo yum install iperf-$(uname -r)

This will install the iperf, iperf-lib and iperf-2.4.20-28.7 RPMs, where ‘2.4.20-28.7’ is the kernel version specified.

Remove this package if you no longer need the runtime iperf for kernel version ‘2.4.20-28.7’. The value ‘2.4.20-28.7’ is just an example. For the running kernel, you can remove the runtime iperf components with:

          % sudo yum remove iperf-$(uname -r)

This will remove the iperf-2.4.20-28.7 and iperf-devel-2.4.20-28.7 RPMs, where ‘2.4.20-28.7’ is the kernel version specified. Also, if this is the last kernel for which iperf was installed, the iperf iperf-lib and iperf-devel RPMs will also be removed.

Note that this is a virtual package name: the actual RPMs installed or removed from the system is a kernel module package whose precise name will depend upon the system being used.

iperf-devel-2.4.20-28.7
Install this package if you need the development iperf package for kernel version ‘2.4.20-28.7’. The value ‘2.4.20-28.7’ is just an example. For the running kernel, you can install the kernel development iperf components with:
          % sudo yum install iperf-devel-$(uname -r)

This will install the iperf, iperf-lib, iperf-devel, iperf-2.4.20-28.7 and iperf-devel-2.4.20-28.7 RPMs, where ‘2.4.20-28.7’ is the kernel version specified.

Remove this package if you no longer need the development capabilities for the iperf package for kernel version ‘2.4.20-28.7’. The value ‘2.4.20-28.7’ is just an example. For the running kernel, you can remove the kernel development iperf components with:

          % sudo yum remove iperf-devel-$(uname -r)

This will remove the iperf-devel-2.4.20-28.7 RPMs, where ‘2.4.20-28.7’ is the kernel version specified. Also, if this is the last kernel for which iperf was installed, the iperf-devel RPMs will also be removed.

Note that this is a virtual package name: the actual RPMs installed or removed from the system is a kernel module package whose precise name will depend upon the system being used.

iperf-lib
This package is an auxillary package that should be removed and inserted automatically by yum(8). In rare instances you might need to remove or install this package explicitly.

6.2.2 Downloading with APT

OpenSS7 repositries support apt(8) repositorie digests and signatures.

6.2.3 Downloading the Binary RPM

To install from binary RPM, you will need several of the RPM for a complete installation. Binary RPM fall into several categories. To download and install a complete package requires the appropriate RPM from each of the several categories below, as applicable. Some release packages do not provide RPMs in each of the several categories.

To install from Binary RPM, you will need all of the following independent packages for your architecture.

Independent RPM

Independent RPM are not dependent on either the Linux kernel version, or the STREAMS package. For example, the source package ‘iperf-source-2.0.8-1.7.2.noarch.rpm’, is not dependent on kernel nor STREAMS package.

All of the following independent RPM are required for your architecture. Binary RPMs listed here are for example only: additional binary RPMs are available from the downloads site. If your architecture is not available, you can build binary RPM from the source RPM (see see Building from the Source RPM).

Architecture Independent
iperf-doc-2.0.8-1.7.2.noarch.rpm
The iperf-doc package contains this manual in plain text, postscript, pdf and html forms, along with the meta-information from the Iperf package. It also contains all of the manual pages necessary for developing OpenSS7 IPERF Utility applications and OpenSS7 IPERF Utility STREAMS modules or drivers.
iperf-source-2.0.8-1.7.2.noarch.rpm
The iperf-source package contains the source code necessary for building the OpenSS7 IPERF Utility release. It includes the autoconf(1) configuration utilities necessary to create and distribute tarballs, rpm and deb/dsc. 10
Architecture Dependent

The following Architecture Dependent packages are required for your architecture. If your architecture is not on the list, you can build binary RPM from the source RPM (see see Building from the Source RPM).

iperf-openss7-2.0.8-1.7.2.i686.rpm
The iperf-openss7 package contains the iperf(1) program compiled to work with the OpenSS7 Linux Native Sockets version of SCTP.
iperf-devel-2.0.8-1.7.2.i686.rpm
The iperf-devel package contains library archives for static compilation, header files to develop OpenSS7 IPERF Utility modules and drivers. This also includes the header files and static libraries required to compile OpenSS7 IPERF Utility applications programs.
iperf-lib-2.0.8-1.7.2.i686.rpm
The iperf-lib package contains the run-time shared libraries necessary to run application programs and utilities developed for the Iperf package. 11
Configuration and Installation

To configure, build and install the binary RPM, See Configuring the Binary RPM.

6.2.4 Downloading the Debian DEB

To install from binary DEB, you will need several of the DEB for a complete installation. Binary DEB fall into several categories. To download and install a complete package requires the appropriate DEB from each of the several categories below, as applicable. Some release packages do not provide DEBs in each of the several categories.

To install from Binary DEB, you will need all of the following independent packages for your architecture.

Independent DEB

Independent DEB are dependent on neither the Linux kernel version, nor the STREAMS package. For example, the source package ‘iperf-source_2.0.8-0_i386.deb’, is not dependent on kernel nor STREAMS package.

All of the following independent DEB are required for your architecture. Binary DEBs listed here are for example only: additional binary DEBs are available from the downloads site. If your architecture is not available, you can build binary DEB from the Debian DSC (see see Building from the Debian DSC).

Architecture Independent
iperf-doc_2.0.8-0_all.deb
The iperf-doc package contains this manual in plain text, postscript, pdf and html forms, along with the meta-information from the Iperf package. It also contains all of the manual pages necessary for developing OpenSS7 IPERF Utility applications and OpenSS7 IPERF Utility STREAMS modules or drivers.
iperf-source_2.0.8-0_all.deb
The iperf-source package contains the source code necessary for building the OpenSS7 IPERF Utility release. It includes the autoconf(1) configuration utilities necessary to create and distribute tarballs, rpms and deb/dscs. 12
Architecture Dependent

The following Architecture Dependent packages are required for your architecture. If your architecture is not on the list, you can build binary DEB from the Debian DSC (see see Building from the Debian DSC).

iperf-openss7_2.0.8-0_i386.deb
The iperf-openss7 package contains the iperf(1) program compiled to work with the OpenSS7 Linux Native Sockets version of SCTP.
iperf-devel_2.0.8-0_i386.deb
The iperf-devel package contains library archives for static compilation, header files to develop OpenSS7 IPERF Utility modules and drivers. This also includes the header files and static libraries required to compile OpenSS7 IPERF Utility applications programs.
iperf-lib_2.0.8-0_i386.deb
The iperf-lib package contains the run-time shared libraries necessary to run application programs and utilities developed for the Iperf package. 13
Configuration and Installation

To configure, build and install the Debian DEB, See Configuring the Debian DEB.

6.2.5 Downloading the Source RPM

If you cannot obtain a binary RPM for your architecture, or would like to roll you own binary RPM, download the following source RPM.

iperf-2.0.8-1.src.rpm
This is the source RPM for the package. From this source RPM it is possible to build binary RPM for any supported architecture and for any 2.4 kernel.
Configuration

To configure the source RPM, See Configuring the Source RPM.

6.2.6 Downloading the Debian DSC

If you cannot obtain a binary DEB for your architecture, or would like to roll your own DEB, download the following Debian DSC.

iperf_2.0.8-0.dsc
iperf_2.0.8-0.tar.gz
This is the Debian DSC for the package. From this Debian DSC it is possible to build binary DEB for any supported architecture and for any 2.4 kernel.
Configuration

To configure the source RPM, See Configuring the Debian DSC.

6.2.7 Downloading the Tar Ball

For non-rpm(1) and non-dpkg(1) architectures, download the tarball as follows:

iperf-2.0.8.tar.gz
iperf-2.0.8.tar.bz2
These are the tar(1) balls for the release. These tar(1) balls contain the autoconf(1) distribution which includes all the source necessary for building and installing the package. These tarballs will even build Source RPM and Binary RPM on rpm(1) architectures and Debian DSC and DEB on dpkg(1) architectures.

The tar ball may be downloaded easily with wget(1) as follows:

     % wget http://www.openss7.org/iperf-2.0.8.tar.bz2

or

     % wget http://www.openss7.org/iperf-2.0.8.tar.gz

Note that you will need an OpenSS7 Project user name and password to download release candidates (which are only available to subscribers and sponsors of the OpenSS7 Project).

Unpacking the Archive

After downloading one of the tar balls, unpack the archive using one of the following commands:

     % wget http://www.openss7.org/iperf-2.0.8.tar.gz
     % tar -xzvf iperf-2.0.8.tar.gz

or

     % wget http://www.openss7.org/iperf-2.0.8.tar.bz2
     % tar -xjvf iperf-2.0.8.tar.bz2

Either will create a subdirectory name iperf-2.0.8 containing all of the files and subdirectories for the Iperf package.

Configuration

To configure and install the tar ball, See Configuring the Tar Ball.

6.2.8 Downloading from CVS

If you are a subscriber or sponsor of The OpenSS7 Project with CVS archive access privileges then you can download release, mid-release or release candidate versions of the Iperf package from the project CVS archive.

The OpenSS7 IPERF Utility package is located in the iperf module of /var/cvs. For release tag information, see Releases.

To access the archive from the project CVS pserver, use the following commands to check out a version from the archive:

     % export CVSROOT='-d:pserver:username@cvs.openss7.com:2401/var/cvs'
     % cvs login
     Password: *********
     % cvs co -r iperf_2.0.8 iperf
     % cvs logout

It is, of course, possible to check out by date or by other criteria. For more information, see cvs(1).

Preparing the CVS Working Directory

Although public releases of the Iperf package do not require reconfiguration, creating a configurable directory from the CVS archive requires tools not normally distributed with the other releases.

The build host requires the following GNU tools:

  • m4 1.4.12
  • autoconf 2.63
  • automake 1.10.1
  • libtool 2.2.4
  • gettext 0.17
  • flex 2.5.33
  • bison 2.3

Most desktop development GNU/Linux distributions wil have these tools; however, some non-development or server-style installations might not and they must be installed separately.14

Also, these tools can be acquired from the FSF website in the free software directory, and also at the following locations:

It should be stressed that, in particular, the autoconf(1), and automake(1), must be at version releases 2.63 and 1.10.1. The versions normally distributed in some mainstream GNU/Linux distributions are, in fact, much older than these versions.15 GNU version of these packages configured and installed to default directories will install in /usr/local/ allowing them to coexist with distribution installed versions.

For building documentation, the build host also requires the following documentation tools:

  • gs 6.51 or ghostscript 6.51, or newer.
  • tetex 3.0 or texlive 2007, or newer.
  • texinfo 4.13a or newer.
  • transfig 3.2.3d or newer.
  • imagemagick 5.3.8 or ImageMagick 5.3.8, or newer.
  • groff 1.17.2 or newer.
  • gnuplot 3.7 or newer.
  • latex2html 1.62 or newer.

Most desktop GNU/Linux distributions will have these tools; however, some server-style installations (e.g. Ubuntu-server, SLES 9 or Fedora 6 or 7) will not and they must be installed separately.16

Note that texinfo 4.12 must not be used as it breaks the build process.

For uncooked manual pages, the entire groff(1) package is required on Debian and Ubuntu systems (the base package does not include grefer(1) which is used extensively by uncooked manual pages). The following will get what you need:

     Debian: % apt-get install groff_ext
     Ubuntu: % apt-get install groff

In addition, the build host requires a complete tool chain for compiling for the target host.

If you wish to package rpms on an rpm(1) system, or debs on a dpkg(1) system, you will need the appropriate tool chain. Systems based on rpm(1) typically have the necessary tool chain available, however, dpkg(1) systems do not. The following on a Debian or Ubuntu system will get what you need:

     % apt-get install debhelper
     % apt-get install fakeroot

To generate a configuration script and the necessary scriptlets required by the GNU autoconf(1) system, execute the following commands on the working directory:

     % autoreconf -fiv iperf

where, iperf is the name of the directory to where the working copy was checked out under the previous step. This command generates the configure script and other missing pieces that are normally distributed with the release Tar Balls, SRPMs and DSCs.

Make sure that ‘autoreconf --version’ returns ‘2.63’. Otherwise, you may need to perform something like the following:

     % PATH="/usr/local/bin:$PATH"
     % autoreconf -fiv iperf

After reconfiguring the directory, the package can then be configured and built using the same instructions as are used for the Tar Ball, see Configuring the Tar Ball, and Building from the Tar Ball.

Do note, however, that make(1) will rebuild the documentation that is normally released with the package. Additional tools may be necessary for building the documentation. To avoid building and installing the documentation, use the --disable-devel or --disable-docs option to configure described in Configuring the Tar Ball.

When configuring the package in a working directory and while working a change-compile-test cycle that involves configuration macros or documentation, I find it of great advantage to invoke the GNU configure options --enable-maintainer-mode, --enable-dependency-tracking and --disable-devel. The first of these three options will add maintainer-specific targets to any generated Makefile, the second option will invoke automat
